Wii dead for good after nand formatter error ?

Hi guys !

the thing is :

My wii has a low brick issue! but i suceed into installing priiloader and i could at least by pressing resert to go to bootmii. The menu of the wii itself, works when it wants. I have to wait up like 24hours unplug to make it work a little bit before crashing.

I tried to format my nand and i follow the guide. It goes right until it says something went wrong with the size of the setting.txt. It was kinda freeze so I press power button and since, it DOESNT work AT ALL (guess i have to say RIP). I lose my 4.1e when pressing gcpad...

When i used the gc pad and press all four directionnal buttons, it used to work and put up on screen my version 4.1E, it's no longer working!

do you think it's really dead this time or should I try to save it again ? what would you advice me to do ?
